Abstract In this paper, SBM-Undesirable model is used to measure the green development efficiency of agriculture in 30 provinces and cities from 2004 to 2015, and the geographic distance matrix and economic geography nested matrix are constructed. The mechanism of agricultural agglomeration affecting the green development efficiency of agriculture is analyzed. The spatial spillover effect of agricultural agglomeration on the green development efficiency of agriculture is empirically tested based on SAR spatial econometric model. The results show that: (1) China’s agricultural green development efficiency has been greatly improved between 2004 and 2015, with obvious regional heterogeneity, showing a declining gradient distribution in the eastern, western, northeastern and central regions. (2) From the extreme difference, the gap between the east, the middle, the west and the northeast is widening, but the level of adjacent provinces and municipalities is narrowing. (3) The efficiency of agricultural green development has positive spatial externalities, but shows a downward trend. Agricultural agglomeration has a significant positive spatial spillover effect on agricultural green efficiency, and the spillover effect is about four times of the direct effect. (4) Agricultural agglomeration has a positive spatial spillover effect on agricultural green efficiency. (5) There is a significant positive spatial spillover effect of agricultural agglomeration on agricultural green efficiency in Northeast and Central China, and the spillover effect is about 0.8 and 1.3 times of the direct effect, respectively, but there is a positive direct effect in West China and the spillover effect is not significant; the eastern region is not significant.
